** Description changed: When specifying vers=4.0 or nfsvers=4.0 in NFSv4 mount options, the client ends up using version 4.2 instead. This option seems to be ignored. This happens with pam_mount and manual mount. We have been using pam_mount for years with the option vers=4.0, but now it appears to be broken. Just recently noticed this is happening while troubleshooting root causes of some other issues on our servers. - Test: mounting manually with option: minorversion=0, the client does not mount, no errors are seen with -vvv, no errors in logs either, it just fails silently. - With pam_mount this option fails as well but is logged as mount failed into auth.log + Test: mounting manually with option: minorversion=0, the client does not mount, no errors are seen with -vvv, no errors in logs either, it just fails silently. + With pam_mount this option fails as well but is logged as mount failed into auth.log ex: Apr 24 17:15:22 servername sshd[666278]: (pam_mount.c:522): mount of /mnt/nfs/home/admin_username failed - I see that something similar was fixed in autofs, but this is not autofs - related. https://bugs.launchpad.net/bugs/1818121 + other nfs4 mount options we are using: + sec=krb5p,noatime,nodiratime,async + + + I see that something similar was fixed in autofs, but this is not autofs related, as we do not use it. https://bugs.launchpad.net/bugs/1818121 Found a similar [oracle] issue but cannot read it= https://support.oracle.com/knowledge/Oracle%20Linux%20and%20Virtualization/2528012_1.html --- Description: Ubuntu 20.04.6 LTS Release: 20.04 --- util-linux: - Installed: 2.34-0.1ubuntu9.6 - Candidate: 2.34-0.1ubuntu9.6 - Version table: - *** 2.34-0.1ubuntu9.6 500 - 500 http://us.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages - 500 http://us.archive.ubuntu.com/ubuntu focal-security/main amd64 Packages - 100 /var/lib/dpkg/status - 2.34-0.1ubuntu9 500 - 500 http://us.archive.ubuntu.com/ubuntu focal/main amd64 Packages - + Installed: 2.34-0.1ubuntu9.6 + Candidate: 2.34-0.1ubuntu9.6 + Version table: + *** 2.34-0.1ubuntu9.6 500 + 500 http://us.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages + 500 http://us.archive.ubuntu.com/ubuntu focal-security/main amd64 Packages + 100 /var/lib/dpkg/status + 2.34-0.1ubuntu9 500 + 500 http://us.archive.ubuntu.com/ubuntu focal/main amd64 Packages mount: - Installed: 2.34-0.1ubuntu9.6 - Candidate: 2.34-0.1ubuntu9.6 - Version table: - *** 2.34-0.1ubuntu9.6 500 - 500 http://us.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages - 500 http://us.archive.ubuntu.com/ubuntu focal-security/main amd64 Packages - 100 /var/lib/dpkg/status - 2.34-0.1ubuntu9 500 - 500 http://us.archive.ubuntu.com/ubuntu focal/main amd64 Packages - + Installed: 2.34-0.1ubuntu9.6 + Candidate: 2.34-0.1ubuntu9.6 + Version table: + *** 2.34-0.1ubuntu9.6 500 + 500 http://us.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages + 500 http://us.archive.ubuntu.com/ubuntu focal-security/main amd64 Packages + 100 /var/lib/dpkg/status + 2.34-0.1ubuntu9 500 + 500 http://us.archive.ubuntu.com/ubuntu focal/main amd64 Packages nfs-common: - Installed: 1:1.3.4-2.5ubuntu3.6 - Candidate: 1:1.3.4-2.5ubuntu3.6 - Version table: - *** 1:1.3.4-2.5ubuntu3.6 500 - 500 http://us.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages - 100 /var/lib/dpkg/status - 1:1.3.4-2.5ubuntu3.3 500 - 500 http://us.archive.ubuntu.com/ubuntu focal-security/main amd64 Packages - 1:1.3.4-2.5ubuntu3 500 - 500 http://us.archive.ubuntu.com/ubuntu focal/main amd64 Packages + Installed: 1:1.3.4-2.5ubuntu3.6 + Candidate: 1:1.3.4-2.5ubuntu3.6 + Version table: + *** 1:1.3.4-2.5ubuntu3.6 500 + 500 http://us.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages + 100 /var/lib/dpkg/status + 1:1.3.4-2.5ubuntu3.3 500 + 500 http://us.archive.ubuntu.com/ubuntu focal-security/main amd64 Packages + 1:1.3.4-2.5ubuntu3 500 + 500 http://us.archive.ubuntu.com/ubuntu focal/main amd64 Packages
